Narcissists cheat.

Not only because it's fun.

And not only because they lack a moral compass.

It's because it's in their nature.

Here's a list of reasons why narcissists cheat and why you better come to terms that they are, will, or really want to:

• Narcissists need a constant stream of supply. Supply gets old, subsequently they need new people to supply them. People can't stay new.
• Narcissists seek instant gratification 24/7. They indulge in porn, chatting, sex and substance abuse, to fulfill that need.
• Narcissists don't love, or emotionally attach to anyone.
• Narcissists don't commit to their partners.
• Narcissists are disloyal.
• Narcissists feel entitled to do as they please.
• Narcissist lack empathy.
• Narcissists put their needs and wants ahead of anything else.
• Narcissists would never deny themselves anything, regardless the consequences for them or their partner.
• Narcissists don't consider their partner in anything they do.

The combination of these factors, makes narcissists extremely prone to cheating on you.

Also, the fact that they need to replace you, before they discard you, makes them cheating on you, inevitable.

Don't kid yourself by saying that yours would never cheat.

Because all that needs to happen for them to betray you, is the opportunity presenting itself.
